7 Claims.

This invention relates in general to dispensing apparatus and moreparticularly to improvements in devices for dispensing material from acontainer in response to gas therein under pressure.

It is an object of this invention to provide a perfume atcmizer in whichthe perfume will be ejected from the container in response to gaspressure.

It is another object of this invention to provide an atoinizer in whichthe liquid to be dispensed and the dispensing gas are contained inseparate reservoirs.

It is a further object of this invention to provide an atomizer in whicha metered amount of perfume will be ejected in response to the singleactuation of its dispensing button.

Other objects and advantages of the invention will be apparent as it isbetter understood from the following description; which, when taken inconnection with the accompanying drawing discloses a preferredembodiment thereof;

In the drawings Figure l is a sectional view of the bottle embodying myinvention;

Figure 2 is a sectional View of a modified form of my invention.

In Figure l, a bottle, which is illustrated as being of glass, containsthe fluid 2, in this case perfume, to be dispensed. The neck 3 of thebottle has a threaded portion 4 engaged with a cap 5. The cap 5 of thebottle is recessed at 6 to support a washer I for a purpose hereinafterdescribed. A discharge nozzle 8 extends laterally from a central opening9 in the cap 5 and is in communication with depending tube It extendingtoward the bottom of the bottle I.

A gas reservoir supporting member I I is seated on the top of the neck 3of the bottle I supported on a circular flanged portion I 2. The cap 5is tightly screwed in place to rigidly hold the reservoir supportingmember II in position. This gas reservoir supporting member II extendsdownwardly and is provided with a threaded portion I 3 at its lower end.The gas containing reservoir I Il is threadingly engaged on portion l?.and contains the dispensing gas I5 therein.

A passage I6 inthe reservoir supporting member II establishescommunication between the chamber formed by II and the dispensing gasreservoir i4, and provides a valve seat for dispensing valve I1, seatedwithin the chamber formed by gas reservoir supporting member I I andbiased upwardly in a manner hereinafter described against the cap 5`.Valve I1 is reduced at either end to form valve portions and at one endis extended to form a stem I8, terminating in a dispensing button I9 onthe opposite side of the washer 1. Valve II is also formed with a springseating ring 2U along its body. Valve spring 2| surrounds valve I'I ndis seated at one end against ring 20 and at its other end on the lowerportion 22 of the chamber II. The valve spring 2I biases valve IIupwardly so that escape from the chamber II is normally prevented.

The operation of this form of my invention is as follows:

The dispensing gas I5, such as aerosoL contained in chamber reservoir I4is partially vaporized to fill the volume or chamber formed by reservoirsupporting member II. Escape of this gas from this chamber, however, isprevented since valve II is biased upwardly by action of spring 2I toclose passage 9. When the operator desires to dispense some of thecontained fluid 2, he depresses button I9 to move valve I'I downwardlyopening the passage 9 and at the same time closing the passage It. Thisallows the gas in the chamber formed by reservoir supporting member IIto escape through passage 9 past nozzle In doing so, the gas sucks upsome of the nuid 2 from the container I, atomizes it and discharges itinto the atmosphere through nozzle 8. It will be recognized that theflow of gas under pressure through discharge nozzle or dispensingpassage 8 lowers the atmospheric pressure above the open upper end oftube Il) and creates a suction therein.

It is obvious that since only a certain amount of gas is released by asingle depression of the button I9, only a certain amount of perfumewill be discharged thereby. When the operator removes his finger frombutton I9, the valve Il is urged upwardly under action of springs 2i toclose passage 9 and open passage i6, thus allowing additional dispensinggas I5 to ll the chamber II. The apparatus is now ready for a secondcycle of operation.

In the form of my invention shown in Figure 2, I have modified mydispensing apparatus so that the amount of perfume dispensed is solelyunder the control of the operator allowing her to dispense any desiredamount in response to a single actuation of the dispensing button. Inthis figure, the subscript a will be added to those parts which aresimilar to those found in Figure 1.

A bottle Ia containing perfume 2a is formed with a neck 3a having athreaded portion 4a is threadingly engaged with a cap 5a. The cap 5a isrecessed at 6a and provided with a washer 1a. A nozzle ila is formed inthe cap 5a in communication with chamber 9a and in communication withtube Illa extending downwardly into the perfume reservoir. Gas reservoirsupporting member lla is formed with a nange portion |2a which restsupon and is held between the neck of the bottle 3a and the cap 5a.Chamber Ha extends downwardly and is formed with a threaded portion i3dat its lower end to which is attached gas reservoir la containing thedispensing gas ia. The chamber lia is in communication with the gasreservoir Ida by virtue of the passage Ia- A valve (1a is seated againstthe cap 5a under spring action. The valve l'a is formed with anextension lila terminating in a button lila. Valve biasing spring 2in'lbears against the cap ld and the washer la to force the valve llaupwardly normally closing passage 9a.

When the operator wishes to dispense perfume from this modication, hemerely pushes the button |90J downwardly allowing the gas [5a to escapechamber 9a through nozzle la causing perfume to be drawn upward throughtube lila and dispensed in the usual manner.

I have described what I believe to be the best embodiments of myinvention. I do not wish, however, to be confined to the embodimentsshown, but what I desire to cover by Letters Patent is set forth in theappended claims.
